Configuration guidelines
Number of X2T mapping entries varies by device. The maximum number of entries is 100 by default, including both entries configured by using the translate ip and translate x25 commands.
When specifying a port number by using the translate ip command, for an IP address using one port, specify port 102; for an IP address using multiple ports, specify port numbers from 1024 to 5000 instead of well known port numbers such as 21, 23 to avoid network failures.
